PLS MAKING Python or R CODE function

Condition 1, If pre-test score X is less than W, then if your highest retake attempt score Q is at least W + S, then test grade will be W + S. Otherwise, it will be Q.

Condition 2, If pre-test score Y is at least W, then if your highest retake attempt score Q is at least X + B, then test grade will be X + B. Otherwise, it will be Q.

ex) W = 5 and B = 5.

If X at least W, Q = W +B = 10 . Otherwise, it will be Q.

If Y at least W, Q = Y + B = 5+5=10 . Otherwise, it will be Q.
